ABSTRACT:
In a double-walled tank for low-temperature liquids, such as a liquid gas, an inner tank forms a primary safety casing while an outer tank, enclosing the inner tank, forms a secondary safety casing. The inner tank includes a base and an upwardly extending side wall with at least the base being formed of metal. Preferably, the outer tank is formed of reinforced concrete. A thermal insulation layer is located between the two tanks, a ring of reinforced concrete encircles the junction of the side wall and base of the inner tank. The ring is L-shaped and in radial section has an upwardly extending leg in contact with the outside surface of the side wall and a generally horizontal leg in contact with the radially outer part of the lower surface of the base.
